CC TDI - Fuel economy

[Guest001]

The ideal way to run a diesel is get it hot and keep it hot. Whilst 400k a week is ok, if you do it in 10 40km runs its not.

I used to drive buses and they were run 16 hours a day and even at 5am the water was still warm after sitting for about 7 hours.

We had two Mercs that had done 800,000 and never had any major parts replaced One hadnt even had injectors.

I only use my Passat where it will get up to temp and stay there for at least an hour and get up to 100km for part of the way.

I have a B7 125TDI Passat sedan which has done over 17,000ks in predominantly inner city driving over the course of 1.5 years of ownership. My daily commute clocks up 30ks and I have never had a problem with regens or lights flashing etc. Once every couple of months I'll go on an extended freeway run with it, but that's it. Occasionally I can hear it doing it's regen when I'm stuck in traffic and it does it without any fuss. In purely inner city driving I can obtain around 850 - 900ks out of a full tank. Even better on the open road where it can notch up approximately 1,000 - 1,100ks out of a tank. I'm sure Hillbilly's advice is most valid, but I really don't think of driving and owning a diesel in those terms. I just drive it like I would any car. The only difference is the fuel economy and performance better any petrol car I've owned in the past.

My wife averages around 400kms a week, the trip from home to school itself is around 18kms each way, plus driving to uni from there is another 20kms or so. Although she won't be reaching speeds of 80kmh+ most of the time, is diesel not a better option than petrol?

For that run diesel will be great!

Thanks Buzy_Robot, that's more what I was after.

Now the question is whether to go for a Passat or CC...

[Buzy_Robot]

Good question, Hadrami! The CC makes for a very striking presence on the road, but when I sat in it, I didn't like the reduced headroom and the relatively poor rear view. Otherwise, I really like the package. Having said that, there's really not that much difference mechanically between the CC and the Passat. Personally, I would go for the Passat and option it with the Sport Pack. Bigger wheels, sharper alloys and CC type sports seats.

Interesting you took a look at the new Mazda6. I used to own one before my current Passat and naturally I'm intrigued by the new one. Totally agree that the pricing of the GT and Atenza variants is absurd and too much of a leap from the Sports and Touring variants. Nevertheless, I do have fond memories of both my incredibly reliable and fun to drive Mazda6 and the exemplary customer service from the Mazda dealer and Mazda HQ.

I'll be trading in my current Passat mid-2013 and who knows what my next car will be ...... decisions, decisions!!

Average economy proven by fortnightly fills is 950-1000ks to the tank at approx 6.1ltr per 100. Canberra has both stop start and long stretches, and so my CC gets the best economy out of all my cars (and believe me I've had a few).

I'm onto my second CC through work and I don't normally see more than 600kms out of a tank with city driving.
The display rarely drops below 7.8L/100.
Country trips is where it shines on 5.3L.

I find our 2.0 TSI Octavia more economical in the city cycle, with it regularly achieving 7.2.
Even my wife managed 6.9 driving back streets from Artarmon to liverpool during morning peak.

Just did a trip to Sydney last Friday, filled up to the brim before leaving and refilled this Friday past for a total of 1035k, 512k freeway @ 115-120 the rest a mixture of Canberra open road and urban driving.. Cc performed beautifully!

After having owned it for around 6 weeks, we're getting around 850kms per tank majority city driving.

Pretty happy with that given that our old Aurion was giving us half of that.

But was the tank the same capacity.

Doing consumption by tankful is fraught with errors and anomalies. Eg Our Polo will do nearly 900 k per tank on a trip.

The Landcruiser I had would do over 1000k on a tank The Polo has a 44 L tank and gets 5.1 K per L The Cruiser has a 145L tank and gets about 11k per L So going on "by the tankful" the Cruiser is as economical as the Polo. NOT.

The only way to check consumption without a special tank is to fill it till you can see the level do the trip and fill it at the same pump to the same level.

Then I will believe your figures. Saying I went from A to B and still had ABOUT half a tank means nothing as gauges can be unreliable to say the least.

One car I had would read 3/4 full for hours and then all of a sudden it was on 1/4. Was a bit disconcerting if you didnt know about it.

There has been some unrealistic figures posted about consumption being better than what the manufacturers advertise.

As their figures are normally done under controlled conditions at optimum performance to achieve them I wouldnt think they could be replicated in normal urban driving.
I would sooner be realistic than optimistic and fool myself into something that may not be correct.
